Issues found in the experiment

The URL is not easy to remember

It's possible to setup a nicer URL for the CDN, but even then, the URL will still read something.cloudfront.net. Unfortunately, we cannot use CNAMEs for this, e.g. use pypi-cdn.python.org as name, since the HTTPS verification would not work with this URL. It would be possible to install a redirect from pypi-cdn.python.org to the something.cloudfront.net URL - at a cost: if the redirector is down, the CDN would not be reachable via the nicer URL.
